Hi,

I would like to send mail from workers via SES?
But its sdk client is kind of Nodejs compatible lib.

Any suggestion?

You can try using

fetch()

fetch()

to send a request to https://docs.aws.amazon.com/ses/latest/dg/send-email-api.html

This example seems to imply that @aws-sdk/client-ses@aws-sdk/client-ses works in workers: https://github.com/winstxnhdw/mail-worker

Hey, I would like to create an API that multiple people can use. People should be able to easily create a token and use it. This token should be linked to their "account". I first tried to do this with unkey, but the cost is too high for me because I think I need a fair amount of "verifications". I recently ran into the hono framework and plan to use it. What do you guys recommend to me?

Adding itty-router-openapi caused issues with jest tests in Cloudflare workers.

Here's the solution:

jest.config.ts

moduleNameMapper: {
'^(yaml|openapi3-ts|@asteasolutions/zod-to-openapi)$': '$1'
},

Better would probably be #general-help if you are using a private ip address then you need to make sure the record isn’t going to be proxied or it will throw errors

thanks ill ask the question there

Stefano•12/26/23, 11:32 PM

Is there a way to interpolate variable names in

.dev.vars

.dev.vars

?

Something like:

VAR_NAME=$VAR_NAME_FROM_SHELL_ENV

VAR_NAME=$VAR_NAME_FROM_SHELL_ENV

Stefano•12/26/23, 11:33 PM

Apparently,

.dev.vars

.dev.vars

is similar to dotenv. And this is possible in dotenv, but haven't been able to make it work in Wrangler.

kian•12/26/23, 11:41 PM

It just uses dotenv.parse to load them

Stefano•12/27/23, 12:14 AM

Ah. @kian Thanks for the heads up.

kian•12/27/23, 12:14 AM

I think the expansion stuff is from the add-on package, dotenv-expand, so not available in Wrangler

What kind of traffic can workers handle if they're being used to serve up static pages from R2? Is there any caching involved?

Unsmart•12/27/23, 4:11 PM

Millions per second for workers. You can use the cache api if you want. You can also use public buckets to add your domain instead of using a worker.

Unsmart•12/27/23, 4:13 PM

R2 can handle a few thousand rps (like 15-20k iirc). But cache can push that further since it won’t hit R2

Chaika•12/27/23, 4:14 PM

Yea R2 would be your bottleneck there, not workers. There's no cache by default with Workers, but you could use the cache api (or use an existing library like kotx/render which does it for you) and save on some Class Bs and faster responses (at the cost of consistency).
If you can use R2 Custom Domains even better pricing wise since you're not paying for the Worker, and then you can just use a Cache Rule to force caching

dave•12/27/23, 5:40 PM

Do cron triggers support smart placement?

kian•12/27/23, 5:42 PM

Nope

ottermanempire•12/27/23, 6:10 PM

Cache was super easy to get running -- thanks for the tip!

ottermanempire•12/27/23, 6:26 PM

Okay, one last question -- is it possible to direct traffic from a client's domain using a cname/similar so example.client.com/endpoint could route to the same worker as nativedomainexample.com/endpoint?

Sounds like a use case for CF for SaaS https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/, special setup for Workers: https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/start/advanced-settings/worker-as-origin/
It's what Pages/R2 use internally for Custom Domains
You'd have to take over the entire hostname/subdomain though, ex: example.client.com, can't just route specific paths. You could of course 404 on all but /endpoint

Will•12/28/23, 10:02 AM

what happened if I need more than 10ms for my operation?

Will•12/28/23, 10:03 AM

let's say 12ms

Will•12/28/23, 10:03 AM

I see that my median worker cpu time is 12ms

Will•12/28/23, 10:03 AM

but not sure why it's still running, cause I have exceeded the limit

Ashley•12/28/23, 11:34 AM

It’s not exact in my experience, I had a worker that would sometimes exceed CPU usage (on the old plans) by 20-30 ms and still “succeed” and some that were 5ms over and fail - the paid plan ($5/month) has a much higher CPU limit per invocation though if you do hit it

Erisa•12/28/23, 11:37 AM

The limit is applied quite loosely and doesnt stop execution unless you go over it by a lot or several times. But as a general rule if your median cpu time is above the limit then even if it didn't trigger this time it might in future so its better to get usage down or switch to a paid plan to avoid interruption
